Francesco unit 2._properties_of_matter

  1. 1. 1 Unit 2. PROPERTIES OF MATTER Francesco Scudellari – Comenius Assistant 2010/2011 Francisco Rodriguez Marín Institute – Osuna (Spain)
  2. 2. 2 What is matter? - Matter is anything that occupies space and can be measured Can you give me some examples of matter?
  3. 3. 3 Examples of matter Everything around us is made of matter rocks water animals plants planets
  4. 4. 4 Properties of matter Two pieces of matter cannot occupy the same space – Example: the sun cannot occupy the same place in space as the moon!!
  5. 5. 5 Bodies of matter, systems of matter Bodies of matter (BODY = CUERPO): Objects having definite limits. Systems of matter: Things with limits that are not precise
  6. 6. 6 a stone a tree the sea a forest a house a seashell Yourself! (=tú mismo/a) a mountain range Which is a body of matter and which a system of matter? BODY (has got definite Ilimits) BODY SYSTEM (doesn’t have precise limits) BODY BODY BODYSYSTEM SYSTEM
  7. 7. 7 Extensive properties of matter • Extensive properties depend on the amount (=cantitad) of matter present – Examples: mass, weight, length, volume This cube of stone has mass of 4 kg, a length of 3 cm, and a volume of 27 cm3 Mass, length, volume depend on the amount of matter present! This cube of stone has mass of 120 kg, a length of 20 cm, and a volume of 4000 cm3 !!!!!
  8. 8. 8 Intensive properties of matter • Intensive properties of matter do not depend on the amount (=cantitad) of matter present Examples of intensive properties: density, color, boiling point (to boil = hervir)
  9. 9. 9 Example They have different volume, length, mass, etc. But they have the same boiling point (100ºC): BOILING POINT IS AN INTENSIVE PROPERTY! A pan full of water A thermal pool At which temperature does the water in the pan boil? At which temperature does the water in the pool boil? 100ºC 100ºC
  10. 10. 10 Matter can be measured • Some extensive and intensive properties can be measured For example, we can measure properties such as: LENGTH (=longitud) (extensive) VOLUME (extensive) DENSITY (intensive) MASS….. (extensive) Do you understand the verb to measure? Can you translate it in Spanish? TO MEASURE = MEDIR
  11. 11. 11 MEASURING LENGTH • Length: the distance between two points We use rulers and measuring tape to determine length RULER MEASURING TAPE In Europe, what are the most common units of measurement for length?
  12. 12. 12 Units of Length:the Ladder Method Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step For example: 15 m = …… cm1500
  13. 13. 13 25 Hm = …… m 1 Km = …..…… mm Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step 725 dm = …….. Dam 1,000,000 2,500 7.25
  14. 14. 14 MEASURING AREA • Area: the space occupied by two dimensions, length × width The area of this rectangle is: 4 × 2 = 8 4 2 What is the unit of measurement for area? Square metres (m )2
  15. 15. 15 Units of AreaKm2 Hm2 Dam2 m2 dm2 cm2 mm2 ×100 for each step ÷100 for each step 15 cm = …… mm 250 mm = …..cm 13 Km = ……… Dam 2.5 1,500 130,000 2 2 2 2 2 2
  16. 16. 16 MEASURING VOLUME • Volume: the total space occupied by a body, length × width × height Example: the volume of a fish tank Volume is measured in …………. Cubic metres
  17. 17. 17 Units of Volume Km3 Hm3 Dam3 m3 dm3 cm3 mm3 ×1000 for each step ÷1000 for each step For example: 12 m = …………. cm 3 3 12,000,000 And 1600 cm = ……… dm 3 3 1.6
  18. 18. 18 MEASURING CAPACITY • Capacity: the total space occupied by a fluid (another way of measuring volume) Example: the capacity of a bottle of Coke or of a fuel tank I am sure you know at least one unit of measurement of capacity. Can you speak its name aloud?
  19. 19. 19 One of the most commonly used units of capacity is…. LITRE
  20. 20. 20 Units of Capacity KL HL DaL L dL cL mL ×10 for each step ÷10 for each step
  21. 21. 21 MEASURING MASS • Mass: the amount of matter in a body – Measured in grams (g) or kilograms (kg) using a scale A scale is not this: A scale is this:
  22. 22. 22 Units of Mass Kg Hg Dag g dg cg mg ×10 for each step ÷10 for each step
  23. 23. 23 MEASURING DENSITY • Density: how concentrated the mass is, mass ∕ volume Example: which object has the higher density, an anvil ( ) or a sponge( ) ? ANSWER: the anvil, because its mass is more concentrated! The unit of measurement for density is…. g/cm (grams over cubic centimetres) 3
  24. 24. 24 TEMPERATURE • Temperature: the degree of hotness or coldness of a body or system; the thermal energy of a body – Measured in degrees Celsius (°C), Fahrenheit (°F), and Kelvin (K) • How do we measure temperature here in Europe?
  25. 25. 25 To measure temperature, in Europe we use………. Celsius degrees! (ºC)
